<h1 id="purpose">Purpose</h1>
<p>The BSP (Board Specific Package) drivers are parts of the STM32Cube package based on the HAL drivers and provide a set of high level APIs relative to the hardware components and features in the evaluation boards, discovery kits and nucleo boards coming with the STM32Cube package for a given STM32 series.</p>
<p>The BSP drivers allow a quick access to the boards’ services using high level APIs and without any specific configuration as the link with the HAL and the external components is done in intrinsic within the drivers.</p>
<p>From project settings points of view, user has only to add the necessary driver’s files in the workspace and call the needed functions from examples. However some low level configuration functions are weak and can be overridden by the applications if user wants to change some BSP drivers default behavior.</p>

<h2 id="main-changes-1">Main Changes</h2>
<ul>
<li>All source files: update disclaimer to add reference to the new license agreement.</li>
<li>Modified the address calculation in the BSP_LCD_FillRGBRect() function when USE_DMA2D_TO_FILL_RGB_RECT is enabled to suppress the display of a distorted shape instead of a rectangle when trying to draw a rectangle with a bigger height.</li>
<li>Cache maintained operation is included in the BSP_LCD_FillRGBRect() function to solve the display issue when USE_DMA2D_TO_FILL_RGB_RECT is enabled.</li>
<li>Remove wrong use of PC6 and PC7 as FMC pins in stm32h747i_eval_nor.c</li>

<ul>
<li>Add explicit definition of “BSP_QSPI_Erase_t” type with 8KB, 64KB and 128KB erase size
<ul>
<li>Notes:
<ul>
<li>The STM32H747I-EVAL comes with a dual flash QSPI, the erase size for each flash is 4KB, 32KB and 64KB</li>
<li>From BSP top view these two flash are seen as a single one with twice the size</li>
